Traditional electrode fabrication methods using organic binders often hinder electron transfer and limit surface area, reducing catalytic performance. Binder-less approaches, such as Ultra-Short Laser Pulses for In-Situ Nanostructure Generation (ULPING), provide an alternative by enhancing electron transfer kinetics and catalytic activity. This study explores the influence of laser fabrication parameters (i.e. laser power and scanning speed) on the growth of nano-Ni/NiO, having broccoli-type morphology, for hydrogen evolution in alkaline media (1 M KOH). SEM and EDX analyses revealed correlations between surface roughness, oxidation, and laser processing conditions, while XPS deconvolution of Ni-2p<sub>3/2</sub> and O-1s spectra provided insights into oxidation states and surface chemistry. Higher laser power increased oxidation and nanostructure formation, leading to enhanced surface area and improved catalytic performance, while lower scanning speeds allowed more ablation time, further improving HER efficiency. Among the four samples studied, sample S3, with highest power and lowest scanning speed, exhibited the best performance with an overpotential of 154 mV at 10 mA/cm², a Tafel slope of 93.8 mV/dec, along with a large ECSA, and stability for 12 hours. Additionally, S3 demonstrated lower charge transfer resistance (R<sub>ct</sub>) and higher catalytic turnover frequency (TOF) compared to other samples. These findings establish ULPING as a scalable, reproducible method for fabricating high-performance Ni/NiO electrodes, emphasizing the importance of optimizing fabrication parameters to enhance catalytic activity, in line with the UN’s Sustainable Development Goals (SDGs) for clean energy technologies.</div></div>","PeriodicalId":13872,"journal":{"name":"International Journal of Electrochemical Science","volume":"20 5","pages":"Article 101004"},"PeriodicalIF":1.3,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143644245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The precursor plays the key role in pursuing such goal. In this paper, LNMO was synthesized by co-precipitation method using two types of precursors (main differences were particle size and surface morphology). The discharge specific capacity of S-LNMO (prepared using smaller-size precursor) can reach high up to 139 mAh g<sup>−1</sup> (1 C = 150 mA g<sup>−1</sup>), with a retention of 92.2 % after 100 cycles. After carefully characterized employing XRD, SEM, BET, in situ XRD and XPS, the origins of better electrochemical performance for S-LNMO could be summarized as follows: firstly, the precursor does not change the crystal structure of the LNMO material. Secondly, a ‘fusion phenomenon’ is observed during charging/discharging cycles in both LNMO materials, but the surface morphological evolutions are various with each other. Thirdly, S-LNMO sample with higher crystallinity and fewer structural defects suffer less from the respiratory effect during long-term lithiation/de-lithiation process. Fourthly, less amount of Mn<sup>3+</sup> diminished the consequence of structural distortion during electrochemical reaction. In addition, the full battery further demonstrates that the structure of the S-LNMO material is more stable.

Based on the principles of CNC machining, tool geometry, and material removal characteristics during the electrochemical anodic dissolution process, this study first employs the finite element method (FEM) to analyze the effects of six different cylindrical cathode working surfaces (d = 2.5, 3, 3.5, 4, 4.5, 5 mm) on the potential and current density in the electrochemical anodic dissolution process, with results validated through a single-factor experiment. The findings indicate that differences in the cathode working surface directly affect the potential, current density, and their distribution on the workpiece surface, thereby influencing the quality and efficiency of electrochemical polishing (EP). Additionally, when the process parameters are the same, a cathode with a diameter of 2.5 mm has a more significant effect on the unit processing area and material removal rate compared to other cathode sizes. Furthermore, insulating the cathode sidewalls enhances localized machining but results in lower processing efficiency, with a surface roughness value higher than that obtained with a conventional cathode. More importantly, EP involves various controllable electrical parameters and peak current effects that can transform spike structures into arcs or rounded corners, thereby forming a smooth, wavy surface. This study combines electrochemical anodic dissolution with CNC machining, providing new insights and methods for enhancing precision interpolation technology and CNC machining quality.</div></div>","PeriodicalId":13872,"journal":{"name":"International Journal of Electrochemical Science","volume":"20 5","pages":"Article 101000"},"PeriodicalIF":1.3,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143593020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
